摘要： A process for the preparation of 2-mercaptobenzothiazole is disclosed. The process comprises heating a reaction mixture comprising nitrosobenzene, hydrogen sulfide and carbon disulfide in a molar ratio of about 1:1.5 to 4:1 to 3, respectively, to a temperature from about 200 to about 300.degree. C., for a time sufficient to convert at least a portion of the reactants into 2-mercaptobenzothiazole. In an alternative process, there is first reacted nitrosobenzene with hydrogen sulfide in a molar ratio of about 1:1.5 to 4, at a temperature from about 20 to about 100.degree. C. for a period of time sufficient to substantially reduce the nitrosobenzene, and subsequently reacting the resulting product mixture with from about 1 to about 3 mole equivalents of carbon disulfide per mole of originally charged nitrosobenzene, at a temperature from about 200.degree. C. to about 300.degree. C.

摘要： A process for the production of thiuram polysulfides substituted by aliphatic, araliphatic and/or cycloaliphatic hydrocarbon radicals is disclosed. In this process, correspondingly substituted secondary amines having a pKa value of .gtoreq.8 are reacted with carbon disulfide and sulfur in a solvent at 0.degree. to 150.degree. C. in the presence of a metal-containing catalyst and oxygen or an oxygen-containing gas.By virtue of its high purity, the thiuram polysulfide obtainable in this way may be directly used for its intended purpose, for example as a vulcanization accelerator or sulfur donor.This process is particularly desirable for the substantially quantitative yields and selectivities and also for its high economy arising from the reaction being carried out in a single stage without expensive auxiliaries and from the elimination of an additional purification step.
